So I was just farming out the Heroic SIVA Crisis playlist and the Dust Palace strike came along. At first it was all going fine, all the doors were opening that should have opened, all the enemies were spawning correctly. Until the penultimate section of the strike when the door to the Cortex wouldn't open. We killed the enemies that spawn in that area but for some reason the door just wouldn't open. We spent about 10 minutes waiting until the first person left. A couple minutes later the next person left. A minute later two more people joined and nothing was changing. So even after all these patches and updates, how has this bug not been fixed yet? Is it also worth noting the keypad beside the door didn't appear until I was on my own?
